Official Explanation
The sentence begins by telling you that Jon only cares about getting an A, and then it says that the team project did not affect his grade. The blank needs a term for how Jon “felt” about the project, and the key words “and because” indicate that the blank will be consistent with the information given. Furthermore, the key word “and” in the last part of the sentence means the blank will be consistent with Jon not doing his share of the work. Predict that Jon will not care about the team project or will feel “indifference” toward it. Answer choice (A) apathy toward is a match for your prediction and the correct answer. Apathy is composed of a- (“not”) and path (“emotion”) and is related to words like empathy, sympathy, and antipathy. Learn these words as a group with the same root.
The word zeal (“strong interest”), in choice (B), is the opposite of what is needed. Note that zealous means “very enthusiastic” and a zealot is “a fanatic” for some cause. Another word beginning with z, zest, also means “great enthusiasm.” Learn these words as a group with related meanings.
Choice (D) cheerful about is incorrect for the same reason; it is positive, but you need a neutral or mildly negative word.
Choice (C) loathing means “extreme dislike,” and choice (E) antagonism toward means “dislike” or “conflict”; both words are too negative. While Jon does not care about the project, he has no reason to hate it. When you studied literature, you may have learned that the protagonist is the main character of the story and the antagonist is the person with whom the main character experiences conflict.
